SubQuery’s Data Indexing Supports Builders on Klaytn

4 min readOct 3, 2023

We are delighted to announce our support for Klaytn, where network participants can now take advantage of SubQuery’s leading data indexer.

Klaytn is a public opensource L1 that focuses on performance and UX, with features such as 1-second block time and immediate finality to provide users with instant transactions akin to Web2, account abstraction, and gas fee delegation to streamline onboarding and everyday usage, and EVM equivalence to simplify development. Since its launch in 2019, Klaytn has since established itself as the dominant L1 in South Korea and is now expanding across Asia by driving blockchain use cases that can create real change in the world, such as RWAs and digital asset ownership.

By integrating SubQuery’s flexible, fast, open, and decentralised data indexing solution, Klaytn developers can organise and query on-chain data for their protocols and applications. The SubQuery API abstracts the backend so that developers can focus on developing products and improving user experiences instead of creating their own indexing software.

We’re always striving to provide developers with the most comprehensive and efficient indexing experience possible, including the open-source SDK, tools, documentation, and developer support that the SubQuery ecosystem provides. Klaytn is also supported in SubQuery’s enterprise-level managed service, which provides enterprise-level infrastructure hosting and handles hundreds of millions of requests each day.

“We have always strived to create a comprehensive and robust network of infrastructure and tooling providers to support our builders. We’re happy to see another multi-chain indexer join our ecosystem, and pleased that developers will be able to utilise SubQuery to build next-gen applications on Klaytn.”

— Sam Seo, Representative Director of Klaytn Foundation

“We’re delighted to announce our support for Klaytn, an innovative platform that offers a unique blend of scalability, user-friendliness, and inclusivity through its well-designed token economy, decentralized governance structure, and commitment to fostering a thriving metaverse. With our cutting-edge APIs and tools, we enable their community to create innovative products and services using their blockchain platform.”

— Sam Zou, Founder and CEO of SubQuery

Why Use SubQuery?

Klaytn developers can now enjoy superior indexing capabilities offered by SubQuery, including access to the open-source SDK, comprehensive tools, extensive documentation, and dedicated developer support within the SubQuery ecosystem. Klaytn is also fully supported by SubQuery’s enterprise-level managed service, ensuring robust infrastructure hosting and handling hundreds of millions of daily requests.

Our experience with customers across all verticals in Ethereum, Polygon, Polkadot, Cosmos, Algorand, NEAR, and Avalanche (such as wallets, networks, explorers, NFT, DeFi, scanners, etc.) has helped us build the best Indexer for developers in web3.

SubQuery is actively working towards decentralising and tokenizing the protocol to establish the SubQuery Network. This network will provide incentivized and verifiable indexing and data servicing to the global community, supporting indexing of projects from Klaytn and other supported blockchains. By integrating Klaytn projects into the SubQuery Network, we aim to enhance data accessibility, incentivize collaboration, and drive innovation within the Klaytn ecosystem.

Klaytn developers will benefit from the superior SubQuery indexing experience, including the open-source SDK, tools, documentation, and developer support that the SubQuery ecosystem provides. Klaytn network participants are now able to use SubQuery’s enterprise-level managed service to manage their own projects, making updates as required.

SubQuery is currently focused on decentralising and tokenizing the protocol to build the SubQuery Network. The SubQuery Network will index and service data from projects to the global community in an incentivized and verifiable way and support indexing Klaytn projects, and those from any other supported Layer-2 from the outset.
